The module is 960 mm wide and 600 mm tall — these are the cutout dimensions for the cabinet door, not the component footprint. Plan the door layout around this opening before ordering the gland plate. ## Firmware compatibility and cable — the gotcha This module requires the 3RW44 soft starter to have firmware version *E05* or later (implemented from May 2006 delivery). If the starter in the panel is older, the display will not communicate — check the firmware revision before cutting the door. The connecting cable (2.5 m, order code 3UF7933-0BA00-0) is not included in the scope of delivery. Budget for it separately; a standard Ethernet patch cable will not work.","metaTitle":"Siemens 3RW4900-0AC00 SIRIUS External Display Module, 960 mm","metaDescription":"Siemens 3RW4900-0AC00 SIRIUS external display and control module for 3RW44 soft starter.
